What are the phases of instruction cycle?
There are four phase of an instruction cycle namely: fetch; indirect; execute; write.
What is a cycling machine?
Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.
What are the different phases of instruction?
There are four phase of an instruction cycle namely: fetch; indirect; execute; write.
What are the four steps for the machine cycle?
Not all the NATO members uses this cycle...The four steps areDirectionCollectionProcessingDisseminationThere are armies that define a fifth step (FEEDBACK) or reduce the cycle to three steps (Direction / Colletion / Processing)

What is instruction cycle with interrupts?
The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.
How would you describe the fetch execute cycle?
Fetch Execute Cycle A more complete form of the Instruction Fetch Execute Cycle can be broken down into the following steps: 1. Fetch Cycle 2. Decode Cycle 3. Execute Cycle 4. Interrupt Cycle 1. Fetch Cycle The fetch cycle begins with retrieving the address stored in the Program Counter (PC). The address stored in the PC is some valid address in the memory holding the instruction to be executed. (In case this address does not exist we would end up causing an interrupt or exception).The Central Processing Unit completes this step by fetching the instruction stored at this address from the memory and transferring this instruction to a special register - Instruction Register (IR) to hold the instruction to be executed. The program counter is incremented to point to the next address from which the new instruction is to be fetched. 2. Decode Cycle The decode cycle is used for interpreting the instruction that was fetched in the Fetch Cycle. The operands are retrieved from the addresses if the need be. 3. Execute Cycle This cycle as the name suggests, simply executes the instruction that was fetched and decoded
What is copper chlorine?
Copper Chlorine is a cycle that is broken up into four steps. It is a thermochemical cycle for making hydrogen.
What is the difference between instruction cycle and machine cycle?
an instruction cycle may consist of a number of machine cycles.
What are the steps in carbon cycle?
The four basic steps of the carbon cycle are the earth, the air, the oceans, and all the organisms that are living. Also called the lithosphere, atmosphere, hydrosphere, and the biosphere.
What is the difference between bus cycle and instruction cycle?
Bus cycle - clock cycles taken to complete one bus transaction. Instruction cycle - clock cycles taken to complete execution of one instruction
What is the relationship between instruction and micro operation?
1 macro can be defined as a cycle involve numbers of small steps to execute or to perform a task this small step is known as micro-opration micro is part of instruction 2.instruction is task performed by micro opration
